Portion of truck cowl hood



FIG. 1 is a front and side perspective view of a portion of a truck cowl hood showing my new design;

FIG. 2 is a top plan view thereof; and,

FIG. 3 is a left side elevational view thereof, the right side being a mirror image thereof.

The portions of the hood shown in broken lines are for illustrative purposes only and form no part of the claimed design. 

I claim the ornamental design for a portion of truck cowl hood, as shown and described.
